AI Technical Summary

Benefits of technology

The modular design facilitates quick and cost-effective maintenance, allows for adjustable air pressure, and extends the lifespan of the machine by reducing wear on the side walls, enhancing the grinding and dehydration process efficiency.

Problems solved by technology

As a result, portions or the entire side wall of the cylindrical would require replacement due to excessive wear.
The replacement of all or a portion of the cylindrical side wall is a difficult task to accomplish as the weld between the original cyclonic comminuter structure and the replacement structure must be air tight due to the utilization of rapidly moving air under pressure.
Accordingly, the configuration of the air inlet slot in the Polifka patent is limited to a relatively small range of pressure that can be fed effectively into the comminuter.

Embodiment Construction

[0040]Referring to the drawings, and particularly to FIGS. 1-3, a cyclonic comminuting and dehydration machine incorporating the principles of the instant invention can best be seen. The cyclonic comminuting and dehydration machine 10 utilizes a flow of low volume, high pressure air to create a vortex within the machine to grind material fed into the machine 10. The machine 10 is formed with an upper cylindrical chamber 12, a lower conical chamber 14, an air infeed mechanism 15, an air discharge apparatus 17 and an infeed mechanism 18 for delivering a flow of material to be ground within the machine 10. The machine is preferably supported in a generally vertical orientation by a support frame 11. The air infeed mechanism 15 includes conduits 16 delivering a flow of high pressure air to the respective air knives 20, as described in greater detail below, for delivery into the interior of the cylindrical chamber 12. Ultimately, air is discharged from the machine 10 upwardly through the...

Abstract

An air knife module assembly and a replaceable wear plate member are provided for a cyclonic comminuting and dehydrating machine. The air knife and wear plate can be formed in a modular configuration with the wear plate being mountable into an opening formed in the side wall of the cylindrical chamber of the cyclonic comminuter. The air knife module can be formed separately of the wear plate member and mounted into an opening formed in the wear plate module. The wear plate module can be secured to the side wall of the cylindrical chamber by removable fasteners while the air knife module can be secured by clamping members mounted on the wear plate module. Sensors in the air discharge detecting hazardous material above a predetermined threshold are operable to affect a de-naturing of the ground material discharge for removal thereof from the discharged stream of material.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to an apparatus for grinding and dehydrating materials and, more particularly, to a modular structure for the input of material into a circular vortex air flow material grinding apparatus.BACKGROUND OF THE INVENTION[0002]Cyclonic comminuting and dehydration machines have been in use to grind various materials while reducing the moisture content in the material. These cyclonic comminuting and dehydration machines are typically formed with an upper cylindrical portion into which is fed a flow of air and a flow of material. The material to be ground becomes entrained in the air flow circling within the cylindrical portion and moves with substantial velocity while in the machine. The cyclonic comminuting and dehydration machine is also formed with a conical portion joined to the cylindrical portion and extending downwardly therefrom. The bottom of the conical portion is formed with a central opening through which the ground ma...
